Cherry tree named ‘BICOLAM’

ABSTRACT

A new and distinct variety of cherry tree denominated ‘BICOLAM’ has fruits that ripen medium in the season, said variety being self-fertile and resistant to cracking, allowing a high production of fruits with large size and light to dark red or two-colored fruit skin, depending on maturity stage, firm, and with a good flavor and eating quality; the fruit is further characterized by its good handling and storage qualities.

Latin name of the genus and species of the plant claimed: Prunus avium (L.) L.

Variety denomination: ‘BICOLAM’.

This application claims priority of Community plant variety right No. 2017/3041 filed on Nov. 23, 2017 (Nov. 23, 2017) which is hereby incorporated by reference in its entirety.

The new variety named ‘BICOLAM’ is also known as 6N.18-2.48.14CE-ASF1607. Indeed, before giving a name to a new and distinct variety of fruit tree, a provisional reference is assigned, considering the references of a tree in orchard. This provisional reference is constituted firstly with the number of the parcel on which the tree has grown, then the number of the line, the tree number and the year of selection. Then before being named ‘BICOLAM’, the provisional reference of this cherry tree variety was 6N.18-2.48.14CE, corresponding to the tree 48 located in line 18-2 of the parcel 6N and selected during the year 2014. The letters “CE” are related to the first letters of the type of tree in French (CE for “CErise”, that means “cherry”). Once the hybrid selected, the breeder assigned a clone reference that begins with the letters “ASF” followed by the year of selection and a number corresponding to the maturity order. The final name is only assigned once the application has been filed and the name approved after its publication in the official bulletin. For the variety ‘BICOLAM’, the clone reference was ‘ASF1607’.

BACKGROUND OF THE NEW VARIETY Field of the Invention

In the field of plant genetics, we conduct an extensive and continuing plant-breeding program including the organization and reproduction of orchard trees, among which peaches, nectarines, apricots, apples, and cherries are exemplary.

It was against this background of our activities that the present variety of cherry tree was originated and reproduced by us in our experimental orchard located near Elne, Pyrénées Orientales, France.

ORIGIN OF THE VARIETY

The present invention relates to a new a distinct variety of cherry tree Prunus avium L. which has been given the variety denomination ‘BICOLAM’. This tree produces fruits with a long shelf life without alteration both on the trees after growth completion and after harvesting, very good eating quality with a cream pink colored flesh, and for fresh market during June in the Pyrénées Orientales department, France.

Contrast is made to ‘FIRELAM’ cherry tree (U.S. Plant Pat. No. 25,564), ‘ROSALOLAM’ cherry tree (U.S. Plant Pat. No. 29,252), ‘BURLAT’ cherry tree (not patented), and ‘FOLFER’ (not patented) cherry tree for reliable description. ‘BICOLAM’ is a promising candidate for commercial success in that it produces very attractive fruits having a long shelf life.

The present new variety of cherry tree (Prunus avium L.) was developed by us in our experimental orchard located in France. ‘BICOLAM’ cherry tree originated in a cultivated area of the South of France, in the Pyrénées-Orientales department where it was also tested. This zone also called Roussillon is subject to a Mediterranean climate. The winter is generally sweet, in relative comparison with other areas of production, regarding the total amount of cold hours lower than 7° C. (Celsius) that varies from 600 hours to 1200 hours, depending on the year. The summer is hot and dry, that is to say the total amount of sunshine hours is an average of 2400 hours to 2800 hours per year. The prevailing wind is called “Tramontane”: it dries the air and clear the sky from clouds, but its intensity can be strong and affect the harvest, fruits quantity and/or quality. Marine moisture does not affect the place. Precipitations are irregular through the year and from one year to another. The amount of rainy days does not exceed 80 days per year and are mostly found in Spring and Autumn. In May and October, very intense precipitations occasionally happen, and the summer is dry with a few thunderstorms.

The ‘BICOLAM’ variety resulted from an open pollination of the cherry tree variety named ‘FIRELAM’ (U.S. Plant Pat. No. 25,564) which was used as the seed parent. Thus, the pollen parent is unknown.

The ‘BICOLAM’ variety was obtained by hybridizing and propagated by grafting on a ‘Maxma14’ (non-patented) rootstock trees. It has been determined to have unique tree and fruits characteristics making it worthy for commercial fresh fruits production. There are no known effects of the standard rootstock tree set forth above on the scion cultivar. Asexually propagated plants remained true to the original tree and all characteristics of the tree and the fruit were transmitted. The plant was asexually reproduced by us in Les Régalines, Route d'Alenya, La Prade de Mousseillous, 66200 ELNE, Pyrénées Orientales, France. More particularly, the plant was reproduced by grafting.

Every known type of grafting adapted to the cherry tree may be performed on the new tree. Especially, the type of grafting will depend on the grafting period and the propagation mode which is used by the nursery owner. Thus, the grafting period may be micrografting at any moment of the year if the grafting is performed in greenhouse, dormant eye shield budding in August or September, growing eye shield budding in June or July.

Compared to its female parent, a red cherry tree named ‘FIRELAM’ (U.S. Plant Pat. No. 25,564), the new variety ‘BICOLAM’ is considered as a two-colored cherry tree or red cherry tree, depending on the maturity stage.

Regarding the flowering period, the flowers of the new variety ‘BICOLAM’ bloom generally slightly later than the flowers of the ‘FIRELAM’ variety. Thus, generally, the flowers of ‘BICOLAM’ bloom 2 to 3 days after the flowers of ‘FIRELAM’.

Moreover, the new variety ‘BICOLAM’ is considered self-fertile whereas the ‘FIRELAM’ variety is not self-fertile and needs to be pollinated by another variety.

Compared to the cherry tree named ‘ROSALOLAM’ (U.S. Plant Pat. No. 29,252), the new variety ‘BICOLAM’ shows a similar maturity period. However, the new variety is self-fertile whereas the ‘ROSALOLAM’ variety is not, such as the ‘FIRELAM’ variety.

Compared to the fruits produced by the cherry variety named ‘BURLAT’ (not patented), that show a weight of about 7.5 to 8 grams, the ‘BICOLAM’ variety produces fruits that are heavier, with a weight of approximately 13 grams and more, and the fruits of ‘BICOLAM’ have a bigger size. The ‘BURLAT’ variety is considered to be sensitive to cracking whereas the new variety ‘BICOLAM’ is resistant to cracking.

Compared to ‘FOLFER’ cherry tree, which is considered to be sensitive to cracking whereas the new variety ‘BICOLAM’ is resistant to cracking. Also, the ripening period for the fruits produced by the variety ‘FOLFER’ is earlier than the ripening period of the new variety ‘BICOLAM’. More particularly, the first fruits of ‘FOLFER’ usually ripen approximately 10 days before the first fruits of the variety ‘BICOLAM’.

SUMMARY OF THE NEW VARIETY

The new variety ‘BICOLAM’ produces fruits of important size, firm, with a semi-sweet flavor, low acidity, and a red color of skin, sometimes a two-colored skin, depending on the maturity stage of the fruits. Indeed, because of their long lasting on trees, the fruits of the new variety ‘BICOLAM’ may either be harvested early while fruits have a two-colored skin, or later with a very luminous light red color covering the whole surface of the fruits, or even later to get dark red fruits. Consequently, depending on the harvesting date, the fruit skin color may evolve from a light red color to a darker red color. The blooming period is medium for the variety, generally at the end of March or at the beginning of April. The maturity period is considered medium, and generally begins at the end of May or early in June, in the South of France. However, it was observed that its date of blooming and maturity seem to be highly dependant on climatic conditions.

DETAILED BOTANICAL DESCRIPTION OF THE VARIETY

The following is a detailed botanical description of the new variety of cherry tree, its flowers, foliage and fruit, as based on observations of specimens grown near Elne, South of France, with color in accordance with The R.H.S. (Royal Horticultural Society) Colour Chart (Fourth Edition) provided by The Royal Horticultural Society of Great Britain.

The trees, flowers and fruits may vary in slight detail due to variations in soil type, cultural practices and climatic conditions.

The main characteristics of this new variety of sweet cherry are a big fruit size with a light to dark red or two-colored skin depending on the maturity stage. The color of fruit flesh is cream to pink. The fruit is firm.

The time of beginning of flowering is medium and the ripening period is also considered medium.

DETAILED DESCRIPTION

Referring more specifically to the pomological details of this new and distinct variety of cherry tree, the following has been observed on trees on their fourth growing season (third year of production) for leaves, fruits and stones, on trees on their fifth growing season (fourth year of production) for flowers and on trees on their sixth growing season (fifth year of production) for trees and trunks, under the ecological conditions prevailing at the orchards located near the town of Elne, Pyrénées-Orientales department, France.

All observations have been done on rootstock cultivar. The rootstock was a ‘MAXMA14’ tree. All major color code designations are by reference to The R.H.S. (Royal Horticultural Society) Colour Chart 2001 (Fourth Edition) provided by The Royal Horticultural Society of Great Britain.

-   Tree: Generally. The first year the cherry tree is generally cut at     2.50 meters height. The length in one year for each lateral shoot     varies from 0.60 meters to 0.80 meters. We are cutting the cherry     trees during the second year to a height of 2.50 meters. The form of     the cheery trees is cylindrical, and the diameter is limited to 1     meter.     -   -   Size.—Medium to high as compared to other commercial sweet             cherry cultivars. The tree size the first year was             approximately 2.50 meters. The tree was pruned during each             following dormant season to a height of approximately 2.50             meters. Current season's shoots growth could reach 0.60 to             0.80 meters. So, the tree size from the second year (second             and next years) reached a final height of 3.10 to 3.30             meters. The mature branches have been pruned to a length of             30.0 centimeters in order to place nets on the trees.         -   Spread.—Approximately 2.0 meters with a cylindrical shape.             The whole orchard was oriented to a central leader             organization, with tree lines spaced of 4.0 meters and trees             spaced of 1 meter in a same tree line.         -   Vigor.—Medium, tree growth reaching 0.60 to 0.80 meters the             first growing season.         -   Productivity.—Good productivity, every year. The new variety             produces adequate fruit set annually on a regular basis. The             number of the fruit set varies with the prevailing climatic             conditions and cultivar practices employed during the bloom             period and is therefore not distinctive of the present             variety.         -   Bearer.—Very regular and quantitative. The extinction of the             clusters of May improves the size and firmness of the fruit.         -   Form.—Semi-spread.         -   Hardiness.—Medium in all stone fruit growing areas of France             and especially where the chilling requirement is between 350             and 1200 hours. No injury with temperatures as low as             −12° C. in winter. Good resistance to late frosts. More             particularly, experimentations on the same orchard in Elne,             Pyrénées-Orientales department, with winter chilling             requirement below 7.2° C. comprised between 700 hours and             1200 hours according to the specificities of the year,             namely 1031 hours in 2012-2013, 777 hours in 2013-2014, 893             hours in 2014-2015, 718 hours in 2015-2016, 825 hours in             2016-2017 and 1017 hours in 2017-2018, showed a good             behavior of the tree in all cases. -   Trunk:     -   -   Size.—Medium.

The leaf gland color evolves with maturity             and, on older leaves, the leaf glands are colored in a brown             red (RHS GREYED ORANGE 172 A). -   Leaf stipules:     -   -   Generally.—No leaf stipules were observed. -   Flowers: -   Flower buds:     -   -   Generally.—At pre-floral stage of development, the floral             bunches are make up with 3 to 4 floral buds having a conic             shape with a round tip. Their form is evolving until             blooming, with variables dimensions. Then, just before             blooming, floral buds have a diameter of about 8.0 to 10.0             millimeters and are approximately 15.0 to 18.0 millimeters             long. The distribution of the flower buds is considered             homogenous on the trees.         -   Color.—This characteristic is dependent upon the proximity             to bloom. At pre-floral stage of development, the bottom of             the flowers buds, or calyx, or flower receptacle, is of             green or light green color at the upper surface (RHS YELLOW             GREEN 153 B or RHS YELLOW GREEN 153 C or RHS YELLOW GREEN N             144 A or RHS YELLOW GREEN 151 A). The lower surface of the             calyx is considered green (RHS YELLOW GREEN 145 A or RHS             YELLOW GREEN 145 B) to brown (RHS GREYED ORANGE 175 A or RHS             GREYED RED 178 A).
